Asteroids, Defender, Gorf, and Jumpman Jr., built from scratch as browser games. No plugins, no downloads, no coins.
I grew up playing three of these games at a small arcade my parents ran on the third floor of a mountain conference center. My dad would open the machines and give me free credits, and I usually had my name in all ten of the high-score spots. The fourth, Jumpman Jr., was a cartridge I played at home on the family Atari — ladders and girders instead of a coin slot. Now I've rebuilt all four to play with my own kids.

Pure vector graphics: thin white lines on black, no fill, no sprites. One playfield that wraps on all four edges, so the screen is the entire world.
Play Asteroids →
A world three screens wide, humanoids to rescue from abductors, and a radar strip that shows you the threats forming off-screen.
Play Defender →
Five different mini-games stacked inside one cabinet, from a Space Invaders-style grid to a wormhole boss fight at the end.
Play Gorf →
A single fixed screen of girders, ladders, and ropes, twelve boards deep, with bombs to defuse and Chopin's Funeral March waiting if you don't.
Play Jumpman Jr. →
